Application filed January 25, 1921. Serial No. 439,786.

To all whom t may concern:

Be it known that I, WALTER S. BECKER, a citizen of the United States, residing at Little Falls, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Lapping Machines, of which the following is a specication.

, This invention hasA reference to lapping machines and particularly to that type operating on the well-known camel back principle and which are adapted for spreading cotton, cotton and woolen waste and other fibres that are used in the making of all grades of batting, and primarily my invention seeks to provide, in a machine of the kind mentioned, means whereby a change from threeto twenty-seven inches wide. can be had and the adjustments readily made, while the machine is in operation, and by Vwhich the stock may be deposited upon the transverse conveyor or apron, in a more uniform'and satisfactory manner than has heretofore been possible.

As is well known, to those familiar with the working of lapping machines of the general type mentioned, some manufacturers of batting use three or four garnets or cards to one unit, with a production of from 800 to 1000 pounds in a working time of ten hours, the speed of the garnets being never changed, no matter what width of lap the mechanism is set for.

At present,'devices are used in connection with camel back types of lapping machines, that provide for producing a lap spread fifteen to eighty inches but so far as I know, when such devices are operated on camel back machines and adjusted to spread a lap lessthan fteen inches wide they cannot be made or arranged to work satisfactorily.

An essential advantage of this invention is the provision of an improved arrangement of parts, constituting the bat width regulating devices, having such cooperative connection and so designed, whereby all of the objections before noted are overcome and which operate for producing laps, no matter what size, from three to twenty-seven inches wide, without the necessity of changing gearsand in which the shifting or changes required for the di'erent sizes of laps, can be conveniently and practically automatically effected without losing in production, which is an important advantage in the art of spreading of all of the different fibres into a lap to be folded or rolled into batting.

Again, my invention seeks to provide simple, comparatively inexpensive and effective attachments for lapping machines of the kind stated, that provide for spreading the different fibres to a uniform condition and by the working thereof it is possible to get uniform thickness and even edges to the laps which, so far as I know, has not heretofore been accomplished by any other devices adapted for spreading all kinds of libres into laps.

`With other objects in view that will hereinafter appear, my invention embodies certain attachments to cotton spreading or lapping machines embodying the peculiar features of construction and novel combination of parts, fully explained in the following detailed description, specifically set out in the appended claims and illustrated in the accompanying drawings, in which:

Figure l is a left hand elevation of my improved mechanism, the same being shown as operatively connected to what is known as a S camel back7 lapping machine, the latter being diagrammatically indicated in dotted lines, the full lines showing my improvements.

Figure 2 is a top plan view of my improved devices or improvements, portions of the machine proper being indicated in dotted lines, the parts thereof being positioned to indicate the ejecting mechanism as in the operative position.`

Figure 8 is a detail elevation of the crank disk with its crank pin adjusting features and the power transmission for driving it.

Figure 4L is a diagrammatic end elevation looking in the direction from left to right in Figure 2, the frame beams, on which the devices are mounted, being shown in section.

ln the drawings, so much of a camel back lapping machine is shown as is necessary to illustrate a practical application of my invention and referring more particularly to Figures 1 and 2 of said drawings, 1 indicates the doffer of a cai-ding or garnet machine, from which the sheet of fibre is delivered to the camel back lapper, the said carding or garnet machine being of any j usual or desired character need not be further referred to.

3 designates the usual short endless conveyor' that transfers the fibre sheet, delivered from the doffer 1 onto the receiving end 0f the usual type of camel back con-V veyor, which consists essentially of the guide The lapper frame includes side portions in which is mounted the transverse conveyor or endlessy apron 15, which is also of the usual or well-known construction and upon which the fibre sheets are laid and lapped in the manner presently more fully explained.

My improvement consists essentially of `two disks. 8 and these are disposed in transverse relation to the lapper frame.

Y The disksl 8 are oppositely positioned and located, one adjacent the inner side of, each of the opposing side beams 217-17v of the said. lapper frame, as is'best shown in Figure 3 of the drawings, by reference to which it willV be observed each disk has a short hub that provides for conveniently iredly mounting the'said disks upon stub shafts 20-20, and each of the stub shafts 2O is journaled in a long bearing 162L formed on a bracket 16 which includes a foot portion for` holding the same fast, at the desired points along their respective side beams 17 the latter, in practice, having a longitudinal series of apertures, whereby to facilitate the placing of the brackets 16--16 at the desiredcpoints along the said beams.

Continuous motion is transmitted to the shafts 20--20 through sprocket wheels 7-7 on the outer ends thereof over which pass chainv drives 6-6 to which motion is imparted, through sprocket gears 5050 on the opposite ends of the driven roll 5 of the Camelback frame, as is clearly shown in Figuresl and 2. Y

Each disk 8 has at least one radiall portion or arm 10 provided with a series of radially disposed internally threaded apertures, in either ofwhich a screw pin 9 can be quickly adjusted, while the machine is in motion, for changing the width travel of the lapping carriage 13, which isdone by changing the pitman bars or arms 11-11, each of which has one end pivotally connected to each end of thel carriage 13, and to the disks 10, at their respective sides of the lapping frame. The screw pins 9 9 engage their respective arms 11 and theyconstitute, asit were, wrist pins for transmitting* reciprocating motion tothe lapping carriage frame from rotary motion constantly imparted to the From the foregoing, taken in connection with the drawings, the complete description, the manner of the practical application and the advantages of my invention will be readt ily apparent to thoseA skilled in the vart to which it appertains.

Briefly stated, the different fibresy are pre,V

pared on the garnets or cardsand is finished on thegarnet doffer land by the workingof the comb 2 the fibres is delivered ontothe apron 3 and then onto the camel back aprons 1 -4 and by the working of therolls 141-14 the fibre is delivered onto the wide traveling apron 15 and through the operation of the sprocket gears 50-50 and chains 6-6 that engage the gears 7--,7, the rotary'V disk devices 3&8 are actuated and transmit, through the armsV 11--11, the desired reciprocations to the lapper carriage 13, the exa-- tentr of movement of which is determined by the particular connection of theV wrist' pins 9 with their disks 8.`

It should be stated my improved means of spreading all kinds offibres isran important factor ,in the manufacture of batting, especially when it is required toV make laps as small as three inches wide.

What I claim is Y 1. In a machine of the character described,

the combination with the main frame and asupplemental supporting frame, the carriage of the camel back lapperA and they transverse apron 'or conveyer mounted on said supplemental frame; means for directly reciprocating the lapper carriage across said Y apron or conveyer, said means comprising rotating disks'mounted on said supplemental frame, pitman bars having one of their ends connected to said carriage and having their other ends radially adjust'ably connected toV said rotating disks, and means'for rotating said disks, said disks and their rotating means beingY located on said supplemental frame above the plane in which said carriage. moves and beneath the camel back conveyer.

frame,the carriage of a camel back lapper andthe endless apron or conveyor mounted on the supporting fra-me; of al pair of oppositely disposed brackets mounted on the mainframe adjacent the entrance end of the camel back7 conveyor,4 a stub shaft mounted 2. In a machine of thecharacter described, the combination with the lappe-r supporting pivotally connected at one end to each end of the lapper carriage, and a Wrist pin connection for the other end of each of the said l0 arms for adjustably joining the said ends of the arnis With the respective disks.
